Vacuum pump

A vacuum pump is a device that removes air and other gases from a sealed space, creating a vacuum—an area with significantly reduced pressure. This process is essential in various applications, including preserving food, manufacturing electronics, and scientific research. The pump works by trapping gas molecules and expelling them, which lowers the number of particles in the space, effectively creating a vacuum. Vacuum pumps can vary in design and efficiency, depending on their intended use, ranging from simple hand-operated pumps to complex industrial systems.
